New USRP2 Warning Message


#1

Hi,

FYI, When I upgraded my gnuradio rev from 10368 to 10404, I got the
following warnning message when I run usrp2_fft.py (although the program
ran
normally):

usrp2::ctor reset_db failed

My OS is Ubuntu 8.1, USRP2 was fitted with RFX900 daughterboard.

Best Regards,

Firas

Thanks. This was a recent addition to libusrp2 to reset the USRP2
daughterboard parameters to power on defaults during host software
initialization.

Do you get this every time you run usrp2_fft.py? Can you try
usrp2_siggen.py or usrp2_rx_cfile.py?

I get this message every time I try to run usrp2_fft.py. for the others,
I will try tomorrow.

Also, when I try to use tb.start, tb.wait & tb.stop with usrp2, I get
the following warning :

usrp2: channel 0 already streaming

When I get this message, usrp2 stops streaming. I got the same behavior
when I use tb.lock and tb.unlock (the flowgraph runs only for one time).

Did this start occurring at the same time as the reset_db() failure,
or has it been going on longer?

For the first part of the question, something about reset_db, I think
you need to update, build and reinstall the f/w on the SDCARD since
internally, we now use a new (internal) method to handle some things.

to latest firmware.

Sorry, it can work. I miss updating the txrx-edk10.1-r10524.bin.

Thanks.

Hello,

Do you solve the problem??
I update the firmware to u2_rev3_ise10.1sp3_r10524.bin.
When I run usrp2/host/apps/test.sh, it still show the error message.

Does anybody has solved the problem?

Thanks.
